PSPVM2

PSPVM2 is the second port of the Parallel Virtual Machine
(PVM) to the ParaStation
system . It is derived from the original PVM source code to retain
compatibility with existing PVM applications and implementations,
but uses a low level interface to the ParaStation system and
direct communication within the ParaStation cluster.

At the time when it was published PSPVM2 was the fastest PVM
implementation on a workstation cluster with a process-to-process
latency as low as 11.5us and a sustained transfer rate of up to
9.4MB/s. It can still be used as part of a larger virtual machine
and all PVM programs can be compiled for PSPVM2 without any
changes.
